If driving to the start:

1) Oatmeal made with milk, PB & J mixed in, one banana mixed in.
2) Orange juice
Depending on if I have time/if the start is NOT at a diner or cafe, then 3) some toast with PB or Nutella

At the start:
1) Some sort of pastry
2) Coffee to 'get things going' if they haven't already

I'm trying to be better with eating on the bike (e.g. preparing sandwiches and not having to eat Clif Bars all the time). Usually I find myself fueling at controles, and then liquid calories (Hammer Perpetuem) in between controles.

I have to say that I enjoy hostel-starts a ton here in Eastern PA. Staying over the night before, and then a breakfast of all of my preferred food, coffee, and bathrooms means I am not scrambling and have plenty of time to dress, eat, take care of business, etc.
